摘要：

(I) BaNiTb2O5 and (II) BaCuLaSmO5 single crystals were prepared by high temperature reactions. The different structure types will be described. (I) crystallizes orthorhombic, space group D2h25-Immm, a = 3.783; b = 5.80; c = 11.407 A ̊; Z = 2. (II): tetragonal, space group D4h5- P4 mbm, a = 6.743; c = 5.836 A ̊, Z = 2. It can be shown that a statistical distribution of La3+ and Sm3+ in (II) leads to a square planar CuO4 surrounding of the BaPtLn2O5 type. © 1990.
